Bladder rhabdomyosarcoma in an infant with Schimmelpenning syndrome

Abstract

Bladder tumors occur more frequently between the fifth and seventh decades of life - they are rare before 40 years of age. Rhabdomyosarcoma is a rare embryonic tumor originating from skeletal muscle tissue. The tumor can appear anywhere in the body, even where there is no skeletal muscle. When located in the genitourinary tract, it can present with hematuria and anuria. The nevus sebaceous of Jadassohn (NSJ) is a congenital hamartoma of cutaneous structures, with epithelial and adnexal origin, present in approximately 0.3% of newborns, and may contain any component of the skin, including sebaceous and apocrine glands or hair. When associated with syndromic features such as mental retardation, central nervous system abnormalities, cardiovascular defects such as the cardiac arrhythmia reported in this case, ocular or skeletal abnormalities, it is called linear sebaceous nevus syndrome, or Schimmelpenning syndrome.
